CAF ALAC
100% private — files never leave your device

Convert ALAC to FLAC for non-Apple players, or MP3 for sharing. If your files are still in CAF format, this page is the shortcut: CAF is Apple's Core Audio container — Logic Pro projects and macOS system sounds live in it, with support for huge files and any codec.

iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the CAF format

CAF (Core Audio Format) is Apple's container for pro audio: 64-bit file offsets for recordings of any length, any codec as payload (PCM, ALAC, AAC), and time-stamped MIDI-style event chunks. Logic Pro exports it and macOS system sounds ship in it.

ffmpeg decodes the common PCM/ALAC payload variants, converting CAF to WAV or MP3 for use in any non-Apple DAW, player or web player.

+ Strengths

  • ✓64-bit offsets — no size ceilings
  • ✓Native to Logic Pro pipelines
  • ✓Flexible codec payload

! Limitations

  • −Apple-centric — rare outside macOS
  • −Some CAF variants (UUID chunks) unsupported
  • −Tag metadata Apple-specific

About the ALAC format

ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.

For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.

+ Strengths

  • ✓Native on every Apple device
  • ✓Open source since 2011
  • ✓Reasonable sizes inside MP4

! Limitations

  • −Outside Apple ecosystems FLAC wins
  • −Slightly worse ratios than FLAC
  • −Confusing .m4a extension doubles as lossy

Why convert CAF to ALAC?

Think of it as moving your file to the container that fits the job. Apple-centric — rare outside macOS ALAC works differently: Native on every Apple device If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.

Frequently asked questions

Is this CAF to ALAC converter really free?

Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.

Are my files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.

Does it work on Windows, Mac, iPhone and Android?

Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.

Is there a file size limit for CAF to ALAC?

The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.

Will converting CAF to ALAC reduce audio quality?

If ALAC is lossless, the output contains everything the CAF file contains — no further loss is added. If ALAC is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.

Can I convert a whole folder of CAF files?

You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
